NAME
Config::Tiny - Read/Write .ini style files with as little code as possible
SYNOPSIS
# In your configuration file
rootproperty=blah
[section]
one=twp
three= four
Foo =Bar
empty=
# In your program
use Config::Tiny;
# Create a config
my $Config = Config::Tiny->new();
# Open the config
$Config = Config::Tiny->read( 'file.conf' );
# Reading properties
my $rootproperty = $Config->{_}->{rootproperty};
my $one = $Config->{section}->{one};
my $Foo = $Config->{section}->{Foo};
# Changing data
$Config->{newsection} = { this => 'that' }; # Add a section
$Config->{section}->{Foo} = 'Not Bar!'; # Change a value
delete $Config->{_}; # Delete a value or section
# Save a config
$Config->write( 'file.conf' );
DESCRIPTION
Config::Tiny
is a perl class to read and write .ini style configuration files with as little code as possible, reducing load time and memory overhead. Most of the time it is accepted that Perl applications use a lot of memory and modules. The ::Tiny
family of modules is specifically intended to provide an ultralight alternative to the standard modules.
This module is primarily for reading human written files, and anything we write shouldn't need to have documentation/comments. If you need something with more power move up to Config::Simple, Config::General or one of the many other Config::
modules. To rephrase, Config::Tiny does not preserve your comments, whitespace, or the order of your config file.
CONFIGURATION FILE SYNTAX
Files are the same format as for windows .ini files. For example:
[section]
var1=value1
var2=value2
If a property is outside of a section at the beginning of a file, it will be assigned to the "root section"
, available at $Config->{_}
.
Lines starting with '#'
or ';'
are considered comments and ignored, as are blank lines.
When writing back to the config file, all comments, custom whitespace, and the ordering of your config file elements is discarded. If you need to keep the human elements of a config when writing back, upgrade to something better, this module is not for you.
METHODS
new
The constructor new
creates and returns an empty Config::Tiny
object.
read $filename
The read
constructor reads a config file, and returns a new Config::Tiny
object containing the properties in the file.
Returns the object on success, or undef
on error.
When read
fails, Config::Tiny
sets an error message internally you can recover via <Config::Tiny-
errstr>>. Although in some cases a failed read
will also set the operating system error variable $!
, not all errors do and you should not rely on using the $!
variable.
read_string $string;
The read_string
method takes as argument the contents of a config file as a string and returns the Config::Tiny
object for it.
write $filename
The write
method generates the file content for the properties, and writes it to disk to the filename specified.
Returns true on success or undef
on error.
write_string
Generates the file content for the object and returns it as a string.
errstr
When an error occurs, you can retrieve the error message either from the $Config::Tiny::errstr
variable, or using the errstr()
method.
property_string
This method is called to produce the string used to represent the property in a section. It is passed the section name and property name.
set
This is a convenience is called to set a value found in the parsed config string. It is passed the section name, property name, and value.
